Abstract

A one-dimensional problem is discussed related to a resonance effects as applies to some finite layer of porous liquid-saturated media. It is shown a possibility to generate unidirectional movements of liquid in porous media with such kind of the wave effects. Resonance nature of these processes is investigated and the main role of a fast wave associated with momentum transfer in a skeleton is determined. The wave influence on such media leads to huge average effective pressure gradients.. Important factor in simulation of wave processes is a friction in the skeleton, because it causes qualitative changes in process characteristics.
